WALTER C. CUNNINGHAM, OF ST. PAUL, MINNESOTA.

TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 628,395, dated July 4,1899.

Application filed January 7, 1 8 9 9.

To aZZ whom it may concern.-

Be it known that I, WALTER C. CUNNING- HAM, of St. Paul, in the countyof Ramsey and State of Minnesota, have invented certain new and usefulImprovements in Tobacco-Pipes, of which the following is aspecification.

This invention relates to tobacco-pipes; and it consists in soconstructing the bowl and stem that they may be divided .into two partsfor the purpose of cleaning, as hereinafter shown and described, andspecifically pointed out in the claims.

This invention relates to tobacco-pipes; and it consists in theconstruction, combination, and arrangement of parts, as hereinaftershown and described, and specifically pointed out in the claims.

In the drawings, Figure 1 is a perspective view of the pipe memberhaving the screwthreaded cavity, and Fig. 2 is a similar view of theother pipe member or the one having the screw-threaded projection. Fig.3 is a side elevation of one of the pipe members. Fig. 4 is aplan viewin section on the linemaof Fig. 2. Fig. 5 is a bottom plan view of themember shown in Figs. 2 and 3.

The bowl of the pipe is divided into two parts A A andthe integral stempart thereof is likewise divided into two parts, the division being madevertically and longitudinally, as shown, so that when separated thetobaccocavity 19 and the smoke-channel b will be exposed throughouttheir entire lengths, so that all the parts with which the tobacco and,the products of the combustion come in contact can be readily cleansedand kept free from the accumulation of nicotine and other deleterioussubstances.

A circular oifset e is formed upon the part A, partially encompassingthe half of the tobacco-cavity b in the part A and provided with anexternal scre'w thread and adapted to engage aninternal screw-thread ina recess in the part A the recess being indicated at a in Figs. 1 and 4,the recess partially encompassing the half of the tobacco-cavity bin thepart A By this simple arrangement, as before stated, every part of thetobacco cavity b and the whole length of the smoke-channel Z2 is exposedwhen thetwo parts A A are sepa- $erial No. 701,478. (No model.)

rated, so that all the parts with which the tobacco or the products ofthe combustion come in contact can be thoroughly cleansed and kept freefrom the accumulation of nicotine or other deleterious matter. Then bythe means of the coaction of the screw-threaded recess in the part A andthe screw-threaded lug on the part A the two parts are firmly united andheld rigidly in contact, while the ferrule clamps the stem-sectionstogether and prevents displacement when not in use. By thus securing thetwo parts together no separation along the line of the union'between thetwo parts can take place, but the joint will be maintained at all timesin a smoke and nicotine tight condition. This forms a very simple andeffective means for fastening the two parts A A together, thejuncturebeing completed and rendered more effective by the taperedferrule D of the mouthpiece, as shown, which when in place firmlybindsthe two parts of the stem together.

Having thus described my invention, what I claim as new is 1. As a newarticle of manufacture, a smoking-pipe formed in two parts dividedlongitudinally through the bowl and stem so that onehalf thetobacco-cavity in the bowl, and onehalf the smoke-cavity in the stem isin each section, and with one part provided with a recess partiallyencompassing the tobacco-cavity therein, and with an internalscrew-thread within said recess, and with the other part provided with aprojection partially encompassing the tobacco-cavity therein, and withan external screw-thread upon said projection adapted to engage thescrew-thread in said recess, whereby all parts of the interior of thepipe are accessible when the parts are separated and the two partsfirmly united, substantially as set forth.

2. As a new article of manufacture, a smokin g-pi pe formed in two partsdivided longitudinally through the bowl and stem so that onehalf thetobacco-cavity in the bowl, and onehalf of the smoke-cavity in the stemis in each section, and with one part provided with a recess partiallyencompassing the tobacco-cavity therein, and with an internalscrew-thread within said recess, and with the other part provided with aprojection partially enccmmy hand in the presence of two subscribingpassing the tobacco-cavity therein, and with witnesses. an externalscrew-thread upon said projection adapted to engage the screw-thread insaid WALTER OUNNlNGHAM' 5 recess, and a ferrule enclasping the dividedIn presence of stem, substantially as set forth. LEWIS D. MANN,

In testimony whereof I have hereunto set C. N. WVOODWARD.
